l Be it known that I, ALBERT C. SCHULZ, a

citizen of the United States, and a resident y repair or replacement of the same by a newY one `canvbe effected. Vhile susceptible o1"V general application, my invention is particularly useful in conneotionwith cooling systems of internal combustion engines, such as those of motor vehicles, aeroplanes, and in other similar situations where light weight is yan important consideration, and the chancev of injury by collision or by being4 struck by atmissile is very great. It is evident that under such conditions of use,the ability tomake a hasty repair is a great advantage.

Myf invention will be best `understood reference to the following description, whentaken in. connection with the accompanying` illustration of one specificembodiment thereof, while its scope will be more particularlypointed out in the appended claims.v

In the drawings: Fig. l is a front elevation ofa sectional `radiator embodying my invention; Fig.` 2 is a vertical sectional view on line 2 2 oftFigl;`

and

Figii: is a' detail sectional View on line 4J-lief Fig. 2.`

1 Referring to the drawings, and to the embodiment of my invention which I have selected for illustration, Ihave there shown` a "radiator comprising two reservoirs 5 and 6 which, 'inthe present example, are placed one above thevother,` and are `connected by uprights 7, constituting tie pieces Irigidly connecting lthe. reservoirs. If deslred, the

Fig. 3 is a plan of the lower reservoir;

reservoirs may be further tied. together vby other uprights 7, in the form of tie-rods disposed adjacent the front andrear faces of `the radiator intermediateV `the uprighjts T and serving to prevent distortion of the intermediate portions of the reservoirs. `The upper reservoir 5 is provided with a chainber 8 having an inlet 9 for the entrance of the cooling medium, usually water, and the iower reservoir 6 isy provided `with a cham` ber 1Q, having an outlet l1 for the Cooling medium.` The upper reservoir is herein provided witha usual tilling aperture 1Q, for the introduction oi' the cooling medium into the system.

Thereservoirs 5 and 6 are provided 'respectively with opposed apertures 13 and 14,

there being several such apertures in each reservoir, the apertures of the upper reservoir beingl separated from each other by ridges or walls l5, and the apertures lli are similarly separated `by ridges or walls i6, which, however, do not separate the reservoirs` into a number of compartments, but v are cored outto provide a free circulation of the cooling medium, thereby preventing the formation of what may be termed steam pockets.

The upper and lower reservoirs 5 and 6. are connectedby one or more, herein a phi rality ot cooling sections, which may be of any suitable type, either cellular or tubularl` the latter, however,being shown as an illustrative form. Each such section, as herein shown, comprises an Vupper header 17, a lower header 18, and one or more,'herein a plurality of, vertical tubes 19, kwhose upper4v and lower ends4 are respectively secured to the upper and lower headers, the latter being perforated for that purpose, whereby communication `is established between the reservoir by way of the opposed apertures 13 and 14with vwhich the tubes directlyv communicate.

In order` toi'naintain the cooperative relation between the cooling sections and the reservoirs, l have herein provided means for producing a relative thrust between thesections and reservoirs lengthwise of the cooling sections,-or, in other words, byvprovidlng means for causing the sections tov press against opposed surfaces of the reservoirs. In thepresent instance, this 1s accomplished by 'providing the reservoirs' and 6 with op- CJD posed converging surfaces and 21, in which the apertures 13 and` 14 are formed, by similarly providing the headers 17 and 18 with converging surfaces 22 and 23, and providingr means for forcing the cooling sections toward the point of convergence of such surfaces, thus producing a wedging action which results in a thrust tending to press the reservoirs apart. Since, however, the reservoirs are firmly tied together, the result must be a forcing of the opposed sui'- faces of the cooling sections, and lthe reservoirs toward each other.

Li s herein shown, have-'provided strips of paclriiigrmaterial 2li and 25, interposed between the opposed surfaces of the cooling sectionsand the upper reservoir on the one hand, and the opposed surtaces of the cooling sections and the lower reservoir on the other hand, such packing material being' provided with apertures corresponding to the apertures in the reservoirs, whereby tie joints are maintained without interfering with the circulation of the cooling medium. 1n the specific example shown, as a. means for forcing the headers against the packing vstrips and the latter against the reservoirs, 1 have provided upper and lower threaded members 26 and 27, herein in the form of studs threaded into the upper and lower reservoirs, and provided with nuts and 29, cooperating with clamps 30 and 31, the latter engaging the front ends of the headers 17 and 18, it being understood that each cooling section is provided with its own individual vclamping means, whereby, should any injury tothat section occur, it may be removed by simply loosening the nuts and swinging the clamps out of engagement with the headers, whereupon the injured section may be withdrawn in a forward direction.

The section may now be repaired or replaced by a new one, as circumstances may require, and if there is not sucient time to make a repair, or if a new section is not at that Amoment available, the communication between the reservoirs afforded bythe injured section n'iay be temporarily interrupted by the use of a pair of thin plates 32 and 38, inserted between the opposed surfaces of the reservoirs and the inner section, the

latter being forced into place between the.

plates, vthus stopping off that particular section temporarily, this being obviously a feature of great practical advantage. Another mode of stopping off an injured section temporarily is to remove the same, plug the ends of the damaged tube, and return the section to its place, the remaining tubes of such section then continuing to act as before.

While I have herein shown and described one form or embodiment of my invention for ilhlstrative purposes, and have disclosed and discussed in seta-il the construction and arrangement incidentalto one specific application thereof, it is to be understood that the invention is limited neitherto the'mere details or relative arrangement of parts, nor to its specific embodiment herein shown, but that extensivedeviations from the illustrated form or embodiment of the invention may be made, without departing fromv the'princiles thereof.
